IRVING, Texas — Dallas quarterback Tony Romo has undergone shoulder surgery and should be ready for off-season workouts when they start in May.

Romo had the procedure Tuesday on the left collarbone that he broke twice last season, causing him to miss 12 games. The recovery time is six to eight weeks.

The first injury came in Week 2 against Philadelphia, and the Cowboys went 0-7 without him on their way to a last-place finish in the NFC East at 4-12. Dallas won in his return at Miami, but he got hurt again in his second game back against Carolina.

Because of Romo’s injuries, the Cowboys are likely to sign a backup in free agency to compete with Kellen Moore, who started the last two games in 2015.
